Eco-friendly Management of Fruit Fly (Bactrocera cucurbitae) Infesting Bitter Gourd

Aims: This study aimed to evaluate some Bio insecticide and management against fruit fly in bitter gourd.
 Study Design: The experiment was laid out at a randomized complete block design with three replications.
 Place Duration of Study: Experimental farm Sher-e-Bangla Agricultural University, Bangladesh during the period from February,2022 july,2022.
 Methodology: consisted seven treatments viz. T1(Lycomax 2g/lit water+ Cutrac+ Yellow Sticky trap+ Sanitation), T2(Lycomax Ceranock+ Cultural control), T3 (Biomax M 1.2 EC+ Cuelure+ trap), T4 (Lycomax 2g/ lit T5 EC + Ceronock+ Cutrac), T6 Sanitation+ control+ Cuelure), T7 (Untreated Control) were used 7 days interval.
 Results: degree (Bactrocera cucurbitae) infestation various phases gourd ripening investigated field lab, as well effectiveness bio-pesticides other control methods combination. Among all highest number captured Lycomax treated plot.Healthy per plant (9.50 fruit/plot) also found T2 plot. whereas maximum amount infested (12.21 fruit/plot), punctures (6.74 puncture/fruit) weight (77.13gm) percentage reduction puncture over resulted treatment plot which 92.58% is near (85.16%) healthy (232.75 gm) came T2. In terms yield (2.54 kg/ plot) gained (T2). From it that except (T7) work effectively infestation.
 Conclusion: It concluded control) best one among trerments.
